Definitions

  • the present invention relates to a thread cutting tap having an elongated body, comprising at a first end a connector portion adapted to be connected to a tool and at a second end a threaded portion for cutting out a thread in a wall of an opening into which said-threaded portion is to be introduced, said threaded portion being provided with at least two cutting edges in the circumferential direction of said body, each of said cutting edges being an integral peripheral part of a flank portion extending substantially radially from the longitudinal extension of said body, said flank portions defining thembetween a chip removal flute in the longitudinal extension of said body for removal of chips cut from said wall, wherein at least one of said flank portions having a side-wall is provided with a chip-breaking member.
  • a thread cutting tap of this kind is known from US-A-2 145 819 .
  • the therein described cutting tap has straight chip removal flutes.
  • Such flutes are disadvantageous, since the transportation of chips is poor, risking to cause accumulation of chips in the flutes. It also suffers from the drawback that it can only be used at relatively low cutting speed.
  • chip-breaking members Another thread cutting tap provided with chip-breaking members is known from SU-A-1 039 661 .
  • the chip-breaking members described in that document are not arranged on a surface of the flank portions.
  • the elongated ridge is an edge formed by the immediate interconnection of said concave surfaces.
  • a sharp and well-defined chip-breaking member is achieved, which allows for a controlled chip-breaking.
  • the elongated ridge is formed by a convex surface.
  • At least said surface is coated by a friction reducing coating.
  • a friction reducing coating is coated by a friction reducing coating.
  • the transport of the chips is improved.
  • the wear resistance is increased.
  • said coating contains a nitride.
  • said coating is anyone of TiN, TiCN, TiAlN, TiAlCN and CrN.
  • a hard surface is achieved.
  • said chip removal flutes are helically shaped over substantially their whole length.
  • the angle between the axial extension of the body and the extension of each of said chip removal flutes is 10°-50°, in particular 10°-25°.
  • said chip removal flutes are partly straight and partly helically shaped, said helically shaped flutes being arranged closest to the second end.
  • the angle between the axial extension of the body and the extension of each of chip removal flutes is 1°-15°.
  • Figure 1A is a side elevation of a prior art straight fluted tap 2 comprising an elongated body having a connector portion 4, a threaded portion 6 and an intermediate portion 8.
  • the threaded portion has, in the longitudinal direction of the body, three flanks 9, 10, 11 (cf. Fig. 1B ) divided by three straight flutes 12, 13, 14.
  • the peripheral part of the flanks 10 is provided with cutting edges 15.
  • the cutting edges 15 divided by the flutes 12, 13, 14 form together a virtual continuous helical thread.
  • the flute 12 is defined by a side-wall 16 of the flank 9 and a side-wall 17 of the flank 10, the side-wall 17 being interconnected to the side-wall 16.
  • the flute 13 is defined by a side-wall 18 of the flank 10 and a side-wall 19 of the flank 11 and the flute 14 is defined by a side-wall 20 of the flank 11 and a side-wall 21 of the flank 9. Furthermore, the side-walls 18 and 19, and the side-walls 20 and 21 are interconnected, respectively.
  • Each of the side-walls 16, 18 and 20 has an elongated concave surface, whereas each of the side-walls 17, 19 and 21 has a pair of elongated concave surfaces divided by an elongated ridge 22 in the form of an edge.
  • Straight fluted taps are suitable for forming threads in through holes as well as in blind holes.
  • the chips may be transported in both directions of the longitudinal extension of the flutes. There is however a risk for accumulation of chips in the flutes.
  • Figure 2A is a side elevation of a helically fluted tap 2' (also called spiral fluted tap). Such a tap is provided with helical flanks 9,10, 11 having side-walls 16, 17 and 18, 19 and 20,21, respectively, defining helical flutes 12, 13, 14 (cf. Fig. 2B ).
  • the angle between the axial extension and the extension of the helical flute is denoted by ⁇ .
  • the flute angle is preferably between 10° and 50°. The best results are however achieved with a flute angle between 10° and 25°.
  • each of the side-walls 16, 18 and 20 has an elongated concave surface
  • each of the side-walls 17, 19 and 21 has a pair of elongated concave surfaces divided by an elongated ridge 22 in the form of an edge.
  • Helically fluted taps are suitable for forming threads in blind holes, as chips will be transported in the flutes in a direction towards the connector portion, i.e. away from the blind hole.
  • Figure 3A is a side elevation of an angularly pointed tap 2" (also called spiral point tap).
  • a tap has threaded portion 6 divided into a straight portion 24 and an angular portion 26.
  • the straight portion has straight flanks 9, 10, 11 having between them straight flutes 12, 13, 14, respectively.
  • the flanks 9, 10, 11 and the flutes 12, 13, 14 are formed angularly in relation to the straight flutes, i.e. angularly in relation to the longitudinal extension of the body.
  • the side-walls 17, 19 and 21 has a pair of elongated concave surfaces divided by an elongated ridge 22 in the form of an edge.
  • Each edge follows the longitudinal extension form of the flanks and the flutes. The edge is thus straight in the straight portion 24 and angular in relation to the longitudinal extension of the body.
  • Angularly pointed taps are particularly suitable for forming threads in through holes, as chips will be transported in the flutes in a direction away from the tap, away from the through hole.
  • the flute angle is preferably between 1° and 15° for best performance.
  • the tap of Fig. 3A is also provided with a lumen 27 for supply of a coolant fluid to the hole where a thread is to be formed.
  • a coolant fluid may be compressed air or an emulsion of oil and water or oil and air.
  • FIG. 4 is shown an alternative chip breaking member. Instead of an edge between the concave surfaces, a convex surface forming a ridge 22 is provided for interconnection thereof.
  • the surface of the side-walls 16 - 21 defining the flutes 12 - 14 is provided with a coating 28 containing a nitride, such as TiCN, TiN, TiAlN, TiAlCN or CrN.
  • a coating 28 containing a nitride such as TiCN, TiN, TiAlN, TiAlCN or CrN.
  • the coating reduces the friction of the surface and also increases the hardness and the wear resistance thereof.
  • the threads of a tap may be provided with a friction reducing coating for reducing the friction while cutting the threads.
  • the chip flutes of that tap are not provided with a coating.
  • taps described in connection with figures 2A, 2B and 4 may be provide with a lumen for supply of a fluid.
  • the number of flanks and flutes, respectively may be more or less than three.
  • a piece of metal is provided with a through hole or a blind hole, either by drilling or by moulding.
  • a thread cutting tap according to the invention and having a general diameter slightly larger than the hole is used.
  • the tap is rotated about its longitudinal axis while applying some pressure thereon, such that it cuts it way into the hole and forms threads.
  • chips are cut away from the wall of the piece of metal defining the hole; owing to the chip-breaking member, the chips are small; and the chips are transported away in the at least partly helical chip removal flutes.
  • the thread cutting tap according to the invention is allowed to be utilised at high cutting speeds.
